"We deeply appreciate Australia's strong support for our armed forces to train here and we wish to thank both the Australian government as well as the local communities for welcoming us so generously."

Mr Lee said the relationship between the two countries was not just about defence, but also education, trade, tourism and culture.

He joined Prime Minister Julia Gillard in celebrating the relationship between the two countries, calling Australia a "trusted friend" of Singapore.

Mr Lee also backed Australia's current bid for a seat on the United Nations Security Council.
